Nehurombo, iyo yazvino yekuyedza system ine matambudziko akakomba. Dzimwe dzenyaya idzi dzagara dzichizivikanwa, sekuti kuongororwa kunodhura kana kuti kunokuvadza kana kuuraya mhuka dzakawanda. Pamusoro pezvo, dambudziko guru nderekuti kuyedzwa hakushande sekuda kwesainzi.
Masayendisiti paanoongorora kemikari, anenge achiedza kuona kuti hazvina ngozi here kuti munhu aonekwe nekamwe kashoma kemuyedzo kwemakore akawanda. Masayendisiti ari kuedza kupindura mubvunzo wekuchengetedzwa kwekugara kwenguva refu kune zvishoma zvezvinhu. Asi kudzidza mhedzisiro yenguva refu mumhuka kwakaoma nekuti mhuka zhinji hadzirarame kwenguva refu, uye masayendisiti anoda ruzivo nekukurumidza kupfuura hupenyu hwechisikigo hwemhuka. Saka masayendisiti anofumura mhuka kumwero wakakwirira zvikuru wemakemikari—mwero wepamusoro mukuedzwa kazhinji kazhinji unoratidza zvimwe zviratidzo zvokuwandisa.
Kutaura zvazviri, vatsvakurudzi vanogona kushandisa kuwanda kwekemikari iyo yakakwira nezviuru zvakapetwa kupfuura zvingazoonekwa nemunhu chero upi zvake mukushandiswa chaiko. Dambudziko nderekuti nenzira iyi, mhedzisiro yacho hairatidzike zviuru zvenguva nekukurumidza. Zvese iwe zvaunogona kudzidza kubva kune yakakwira dose kuyedza ndizvo zvinogona kuitika mumamiriro ekudarika.
Rimwe dambudziko rekuongorora mhuka nderekuti vanhu havangori makonzo makuru, mbeva, tsuro, kana dzimwe mhuka dzekuyedza. Chokwadi, pane zvimwe zvakakosha zvakafanana mubaiology biology, maseru, uye organ system, asi kune zvakare misiyano inoita mutsauko mukuru.
Zvinhu zvina zvakakosha zvinobatsira kuona kuti kufumurwa kwemakemikari kunobata sei mhuka: kuti kemikari inotorwa sei, inogoverwa mumuviri wese, yakagadziriswa uye yakaburitswa. Aya maitiro anogona kusiyanisa zvakanyanya pakati pezvipenyu, dzimwe nguva zvichitungamira kune misiyano yakakosha mumhedzisiro yekuratidzwa kwemakemikari.
Vatsvakurudzi vari kuedza kushandisa mhuka dziri pedyo nevanhu. Kana vane hanya nemigumisiro inogona kuitika pamwoyo, vanogona kushandisa imbwa kana nguruve - nokuti maitiro ekutenderera kwemhuka idzi akafanana nevanhu kupfuura mamwe mhuka. Kana vane hanya nehurongwa hwemagetsi, vanogona kushandisa katsi kana tsoko. Asi kunyangwe paine kuenderana kwakanaka, misiyano pakati pemarudzi inogona kuita kuti zviome kushandura mhedzisiro yevanhu. Misiyano midiki mubiology inogona kuita mutsauko mukuru. Semuenzaniso, mumakonzo, mbeva uye tsuro, ganda rinokurumidza kutora makemikari - zvakanyanya kukurumidza kupfuura ganda revanhu. Saka, kuedza kushandisa mhuka idzi kunogona kuwedzeredza ngozi dzemakemikari anotorwa neganda.
Sekureva kweUS Food and Drug Administration, inodarika 90% yemishonga mitsva inovimbisa inokundikana mukuedzwa kwevanhu, kungave nekuti iwo makomboni haashande kana nekuti anokonzera akawandisa maside effects. Nekudaro, imwe neimwe yeaya makomisheni akamboyedzwa zvakabudirira mune dzakawanda bvunzo dzemhuka.
Kuongororwa kwemhuka kunotora nguva uye kunodhura. Zvinotora makore angangosvika gumi nemadhora zviuru zvitatu kuti apedze zvidzidzo zvese zvemhuka zvinodiwa kunyoresa mushonga wezvipembenene neUS Environmental Protection Agency. Uye bvunzo dzechinhu chimwe chete ichi chemishonga inouraya mhuka dzinosvika gumi - mbeva, makonzo, tsuro, guinea pigs nembwa. Kune makumi ezviuru zvemakemikari akamirira kuongororwa pasi rose, uye kuyedza imwe neimwe inogona kudhura mamirioni emadhora, makore ebasa, uye zviuru zvehupenyu hwemhuka. Zvisinei, iyi miedzo haisi vimbiso yekuchengeteka. Sezvatataura pamusoro apa, isingasviki 10% yemishonga mitsva inogona kubudirira kukunda miedzo yevanhu. Maererano neimwe nyaya iri mumagazini yeForbes, makambani anogadzira mishonga anopedza avhareji yemabhiriyoni gumi emadhora kugadzira mushonga mutsva. Kana mushonga ukasashanda, makambani anongorasikirwa nemari.
Nepo maindasitiri mazhinji achiramba achivimba nekuyedzwa kwemhuka, vagadziri vazhinji vari kutarisana nemitemo mitsva inorambidza kuedza zvimwe zvinhu pamhuka. European Union, India, Israel, São Paulo, Brazil, South Korea, New Zealand, neTurkey dzakatora zvirambidzo pakuongorora mhuka uye/kana kurambidzwa kutengeswa kwezvizoro zvakaedzwa. Iyo UK yakarambidza kuongororwa kwemhuka kwemakemikari emumba (eg kuchenesa nekuwacha zvigadzirwa, zvinofefetedza mweya). Mune ramangwana, nyika dzakawanda dzichatora zvirambidzo izvi sezvo vanhu vazhinji vachiramba kuongororwa kwemakemikari pamhuka.
